Nut () for moving a strip for transporting powder in a selective additive manufacturing apparatus, having a tapped hole () extending along a first axis (A), characterized in that it comprises a slot () which passes through the thickness of the nut from an external surface of the nut () to the internal surface () of the tapped hole () and which extends along a plane passing through the first axis (A) over at least one thread pitch () of the tapped hole ().

Nut having a slot for a selective additive manufacturing apparatus

An inertable container () for transporting an additive manufacturing powder comprises an inertable volume () and a main opening () granting access to the inside of this inertable volume, the inertable volume () comprising an upper portion () and a lower portion (), the main opening () being located in the lower portion () of the inertable volume, and the section (S) of the inertable volume () increasing gradually over at least part of the height (H) of the container () and from the lower portion () towards the upper portion () of the inertable volume. The main opening is equipped with a passive half-valve () allowing this main opening () to be closed in such a way as to be sealed in an airtight and humidity-proof manner. The container comprises at least two inerting tappings.

Inertable container for transporting an additive manufacturing powder

A powder bed fusion additive manufacturing machine () comprises: a manufacturing chamber (), at least one mobile powder-receiving surface () and a manufacturing zone () situated inside the manufacturing chamber, a powder-spreading device (), and at least one powder-distribution device () distributing powder over the mobile receiving surface. The distribution device comprises a buffer reservoir () connected to a powder supply (), and a powder-distribution point (P) beneath which a mobile receiving surface () moves, and the powder-distribution device comprises a screw-type metering device () connecting the buffer reservoir () and the powder-distribution point (P) and enabling the generation of a continuous stream of powder from the buffer reservoir towards the powder-distribution point.
